A outer cardboard box is provided for an inner bag, the box having a spout so that viscous, creamy or pasty material can be dispensed from the spout. In this box, the bottom wall opposite to the pouring spout is connected with only two sidewalls so that when the sidewalls are compressed to cause a flow of material from the inner bag and through the spout, the bottom wall bulges inwardly and the other sidewalls bulge outwardly.
